Bottom Line: Unusual sites for this disease can cause diagnostic problems.This pictorial essay illustrates various radiological findings of HD in the liver, spleen, kidney, pancreas, peritoneal cavity, omentum, adrenal, ovary, lung, mediastinum and retroperitoneum.Familiarity with the imaging findings of HD may be helpful in making an accurate diagnosis and preventing potential complications.

ABSTRACT
Hydatid disease (HD) is an endemic illness in many countries, and it poses an important public health problem that's influenced by peoples' socioeconomic status and migration that spreads this disease. Although rare, it may occur in any organ or tissue. The most common site is the liver (59-75%), followed in frequency by lung (27%), kidney (3%), bone (1-4%) and brain (1-2%). Other sites such as the heart, spleen, pancreas and muscles are very rarely affected. Unusual sites for this disease can cause diagnostic problems. This pictorial essay illustrates various radiological findings of HD in the liver, spleen, kidney, pancreas, peritoneal cavity, omentum, adrenal, ovary, lung, mediastinum and retroperitoneum. Familiarity with the imaging findings of HD may be helpful in making an accurate diagnosis and preventing potential complications.

Type I hydatid cyst of the liver in an 11-year-old girl. Unenhanced CT scan of the upper abdomen shows a large unilocular hydatid cyst (18 HU) with a high-attenuation wall in the subdiaphragmatic portion of the liver (arrow).

Figure 1: Type I hydatid cyst of the liver in an 11-year-old girl. Unenhanced CT scan of the upper abdomen shows a large unilocular hydatid cyst (18 HU) with a high-attenuation wall in the subdiaphragmatic portion of the liver (arrow).

Mentions: A pathology-based classification for this disease has been described by Lewall (1). The early lesions (type I hydatid cysts [HCs]) have a non-specific anechoic cystic appearance on ultrasonography (US) (1-4). On CT scans, Type I HC appears as a well-defined, round or oval cystic mass with an attenuation density near that of water (3-30 HU) (Fig. 1). On magnetic resonance imaging (MRI), HC is seen as hypointense on T1-weighted images and as marked hyperintense lesions on T2-weighted images. MRI can displays a low-signal-intensity rim that surrounds the cyst (the "rim sign"), which is more evident on the T2-weighted sequences (2, 8).
